SEAL-LOCK.

SFEGIFICATION forming part of Letters Patent No. 285,384, datedSeptember 25, 1883.

I Application filed May 9, 1893. (No $1nodel.)

To a/Z whom t may concern,.-

Be it known that I, EDWARD J. Bnooiis, a citizen of the United States,residing at East Orange, in the State of New Jersey, have in- 5 vented anew and useful Improvement in Seal- Locks, of which the following is aspecification.

My present invention consists in a glass-seal padlock having itskey-hole and a horizontal seal-holding recess in its bottom, with anopening at one edge to receive the seal and a vertically-moving gateactuated by the shackle of the lock to retain the seal, whereby I amenabled to insert the seal edgewise with facility, and to vfasten itinthe act of locking theshackle of the padlock without eXtra motions orcomplication of parts, while at the same time the seal is effectivelyprotected by its position,and the key-hole is securely covered bytheseal itself` without extraneous aid.

A sheet of drawings accompanies this speciiication as part thereof.Figure l of these drawings is a front elevation of my said selflockingglass-seal padlock and its unlockingkey. Fig. 2 is aback view of thefront or main part of the lock-shell with the works` therein,illustrating by dotted lines the unlocking operation. Figs. 3, 4, and 5represent vertical transverse sections on the lines correspondinglynumbered. Fig. (i is arbottom View of the unsealed lock, and Fig. 7 isan'edge view of the key.

Like letters of reference indicate corresponding parts in the severalfigures.

The shell of the padlock consists of two castings, A B, which maybe ofiron or brass, and three smaller castings of the same metal Aconstitute,respectively, a shackle, C, a lever-bolt, D, and a gate/7 E, whichtogether with two spiral springs, s Ss, complete the lock. The jointbetween the parts A B is central and parallel to the face of the lock,and a hinge-notch, 71, and mouth m, to receive the shackle O, a mainrecess, r, a seal-holding recess, rr, and a keyhole, L, are formedjointly in the two parts, as seen in Figs. 2 to 5, inclusive, the latterand said seal-holding recess being located in the bottoni of the lock,as best seen in Fig. 6. The parts A B are securely united byfour rivet-Fig. 2, cast on the former, and the shackle O is strongly and safelyhinged in said hinge-notch h by means of closely-embraced trunnions t,cast on the shackle, and4 a pintle, pp, cast on the part A, andterminating within a socket, q, in the part B, as seen in Fig. 3. Themouth m is surrounded by a wall, fw, embraced by a corresponding recessin the nose end of the shackle, to exclude water, and the shackle atthis end terminates in a long bev- `eled nose, n, having a notch in its'front edge to receive the nose of the bolt D, which is correspondinglybeveled to render the padlock self-locking.

The gate E is arranged below and in line with the shackle-mouth m, asseen in Figs. 2 and 4, and it has a central stem, guided by a projectionwithin the part A and embraced by the spring ss above the projection. Asuitable head, hh, mayl be upset or soldered on above this spring. Thegate proper is adapted to extend across and tightly close the open endof the seal-holding recess rr, as seen in Figs. 2 and 4, and in dottedlines in Fig. 6, and is depressed into effective position and heldthereby the nose of the shackle bearing on said head 11.11.. Reacting againstthis head, said spring ss tends to re-elevate the gate and eject theshackle, and so operates when the shackle is released, as illustrated bydotted lines 1n Fig. 2, unless the shackle be locked. A downward bend inthe bolt D forms a square shoulder in i line with its nose, and this isdrilled to receive one end of the spring s, by which the bolt is thrown.lThe body of this spring is supported on all sides by the walls of therecess fr and supplemental projections cast on the parts A B inside, 'asseen in Fig. 5, so as to preclude displacement thereof. The bolt ispivoted near the bottom of the recess r, as best seen in Fig. 2, and hasan upwardly-inclined rigid lever end, Z, to coact with a matchingunlockingkey, K, Figs. l and 7. rIhe key K,being a barrel-key, is guidedand supported within the key-hole k and recess r by a key-pin, fr,depending from the upper spring-supporting projection within the part A,said projection being extended and drilled to receive the pin, which isriveted fast therein. The key-bit consists of two projections, g/ z, thelower of which, when the key is inserted, insures inserting it fully,while the upper, having an inclined lower surface, (best seen in Fig.7,) acts 'I oo upon said inclined lower end, Z, of the bolt D, and turnsthe latter upon its pivot to release the shackle C, as illustrated bydotted lines in Fi 2.

Vhile the padlock is unlocked the gate E remains in elevated position.An ordinary glass seal, S, Figs. 3 and 5, may now be slid lengthwiseinto the open seal-holding recess rr, and the shackle C be passedthrough a staple or pair of staples and snapped shut, when the wholewill be sccurely'locked. The face ofthe seal is exposed within anopening, o, Fig. 6, of ainple size, and it can readily be inspected byturning up the lock', while as the lock hangs it is effectivelyconcealed and protected. The open end ol' the seatholding recess beinglocated at the rea-r en d of the lock with reference to the direction oftravel, (indicated by an ar row in Fig. 1,) rain and dust beat againstsolid walls, and any clogging of the seal-holder is precluded; and untilthe shackle is securely locked its ejection by the reaction of thegatespring ss, as aforesaid, will indicate the fact and preclude leavingthe padlock unlocked by oversight. Preparatory to unlocking, the seal lS is broken by a breaking-poi nt, b, on the key K, or other convenientmeans, and the key is inserted and given a quarter-turn. rlhis drawsback the nose ot' the bolt D, as aforesaid, and allows the gate E torise and ej cet the shackle C. I do not lilnit myself to any particularforni of spring, norto the described 'forni of bolt, but propose usingsprings of any preferred make, and may use, for example, a horizontalsliding. bolt, retracted through the medium of a bellcrank leversiinilar to the lower part of the le ver-bolt D.

I am aware that a seal-padlock having its key-hole in its vertical face,and a sliding keyhole cover to protect the same, has been constructedwith a seal-holding recess below its main recess or lock-chan1ber withina tail-extension of the lock, the seal being inserted flatwise andretained in vertical position beneath said key-hole cover by a slidingbolt, 7 7 which is grooved to receive a portion of the seal, so as tohold the seal in the recess/7 said bolt being actuated by the shackle,and serving to elevate the latter' when unlocked. I ain also aware thatanother seal-padlock is constructed with a recessed bottoni furnishedwith a pivoted sealholder, in which the seal is held within the bottoniof the padlock, so as to be out of sight. In my glassseal padlock Idispense with any key,- hole cover other than the seal itself, and alsowith any holder 'for the seal other than that formed by asini ple recessin the padlock itself.

I claim as new and of niy invention and desire to secure-by LettersPatent- A glass-seal padlock having its key-hole and a horizontalseal-holding recess in its bottoni, with an opening at one edge toreceive the seal, and avertically-inoving gate actuated by the shackleof the lock to retain the seal, substantially as herein specified., forthe pur poses set forth.
